Type material.

Holotype: ECUADOR • 1♀; EC-43493, YY-A138; Napo, Yanayacu Biological Station, Sendero Culo del Mundo, Plot 450; cloud forest; 2,352 m; - 0.590833, -77.896389; 18.xi.2009; Wilmer Simbaña leg.; caterpillar collected in second instar; cocoon formed on 08.xii.2009; adult parasitoid emerged on 08.i.2010; ( PUCE).

Diagnosis.

Vertex in lateral view pointed or nearly so ( Fig. 190C ), dorsal groove on axillary trough of scutellum with carinae only proximally ( Fig. 190F, G ), distal antennal flagellomere longer than penultimate, mesoscutum punctation proximally distinct, but distally absent/dispersed ( Fig. 190F ), temple punctate, propodeum without median longitudinal carina ( Fig. 190G ), petiole on T1 virtually parallel-sided over most of length, but narrowing over distal 1/3, finely sculptured ( Fig. 190H, I ), fore wing with vein 1 cu-a straight, r vein curved, outer side of junction of r and 2RS veins not forming a stub ( Fig. 190L ), dorsal outer depression on hind coxa present, inner margin of eyes diverging slightly at antennal sockets ( Fig. 190B ), and lateral grooves delimiting the median area on T2 clearly defined and reaching the distal edge of T2 ( Fig. 190H, I ).

Coloration

( Fig. 190 A–M ). General body coloration polished black except scape and all antennal flagellomeres (on both sides) brown; pedicel brown, but distally with a brown-reddish ring; apex of mandibles and glossa brown-reddish; maxillary and labial palps light yellow-brown; tegulae brown. Eyes gray/silver and ocelli reddish (in preserved specimen). Fore and middle legs dark yellow except claws brown; hind legs dark yellow, except black coxae, femora distally with a brown dot, 2/3 distal of tibiae and tarsomeres brown, although basitarsus proximally with a yellow band. Petiole on T1 black and sublateral areas yellow; T2 with median area black, adjacent area very narrow with silhouette well-defined, and lateral ends yellow; T3 mostly brown and lateral ends narrow and yellow/yellow-brown; T4 and beyond completely brown; distally each tergum with a wide yellow-translucent band. In lateral view, T1-3 completely yellow; T3 and beyond yellow, but dorsally brown, extent of brown area remaining almost constant, although the most distal tergum completely brown. S1-3 yellow; S4 yellow, but ventrally brown; penultimate sternum and hypopygium brown.

Description.

Head ( Fig. 190 A–D ). Head triangular with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.27:0.08, 0.27:0.08, 0.28:0.08), distal antennal flagellomere longer than penultimate (0.15:0.08, 0.12:0.05), antenna longer than body (3.83, 2.92); antennal scrobes-frons shallow. Face with dense fine punctations, medially with lateral depression, interspaces smooth and longitudinal median carina present. Frons smooth. Temple wide, punctate and interspaces clearly smooth. Inner margin of eyes diverging slightly at antennal sockets; in lateral view, eye anteriorly convex and posteriorly straight. POL subequal in length with OOL (0.12, 0.12). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally pointed or nearly so and dorsally wide.

Mesosoma ( Fig. 190A, F, G, J ). Mesosoma dorsoventrally convex. Distal 1/3 of mesoscutum with lateral margin slightly dented, punctation proximally distinct, but distally absent/dispersed, interspaces wavy/lacunose. Scutellum triangular, apex sloped and fused with BS, but not in the same plane, scutellar punctation distinct throughout, in profile scutellum flat and on same plane as mesoscutum, phragma of the scutellum partially exposed; BS only very partially overlapping the MPM; ATS demilune with short stubs delineating the area; dorsal ATS groove with carinae only proximally. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation nearly at the same level as mesoscutum (flat) and with same kind of sculpture as mesoscutum. Metanotum with BM convex; AFM with a small lobe and not as well delineated as PFM; PFM thick, smooth and with lateral ends rounded; ATM proximally with a groove with some sculpturing and distally smooth. Propodeum without median longitudinal carina, proximal half curved with medium-sized sculpture and distal half relatively polished and with a shallow dent at each side of nucha; distal edge of propodeum with a flange at each side and without stubs; propodeal spiracle distally framed by a short transverse carina; nucha surrounded by very short radiating carinae. Pronotum with a distinct dorsal furrow, dorsally with a well-defined smooth band; central area of pronotum and dorsal furrow smooth, but ventral furrow with short parallel carinae. Propleuron finely sculptured only ventrally and dorsally without a carina. Metasternum convex. Contour of mesopleuron convex; precoxal groove smooth, shiny and shallow, but visible; epicnemial ridge convex, teardrop-shaped.

Legs. Ventral margin of fore telotarsus slightly excavated and with a tiny curved seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.15, 0.08). Hind coxa with dorsal half sparsely punctate, ventral half densely punctate, and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.46, 0.30), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus as equal in length as fourth tarsomere (0.15, 0.15).

Wings ( Fig. 190L, M ). Fore wing with r vein curved; 2RS vein straight; r and 2RS veins forming a weak, even curve at their junction and outer side of junction not forming a stub; 2M vein slightly curved/swollen; distally fore wing [where spectral veins are] with microtrichiae more densely concentrated than the rest of the wing; anal cell 1/3 proximally lacking microtrichiae; subbasal cell with microtrichiae virtually throughout; veins 2CUa and 2CUb completely spectral; vein 2 cu-a present as spectral vein, sometimes difficult to see; vein 2-1A proximally tubular and distally spectral, although sometimes difficult to see; tubular vein 1 cu-a straight, incomplete/broken and not reaching the edge of 1-1A vein. Hind wing with vannal lobe narrow, subdistally and subproximally straightened, and setae evenly scattered in the margin.

Metasoma ( Fig. 190A, H, I, K ). Metasoma laterally compressed. Petiole on T1 finely sculptured distal, but only laterally, virtually parallel-sided over most of length, but barely narrowing at apex, apex truncate (length 0.45, maximum width 0.20, minimum width 0.17), and with scattered pubescence concentrated in the first distal third. Lateral grooves delimiting the median area on T2 clearly defined and reaching the distal edge of T2 (length median area 0.18, length T2 0.18), edges of median area polished and lateral grooves deep, median area broader than long (length 0.18, maximum width 0.30, minimum width 0.12); T2 with scattered pubescence only distally. T3 longer than T2 (0.25, 0.18) and with pubescence more notorious in distal half. Pubescence on hypopygium dense.

Cocoon ( Fig. 190E ). White lace-shaped cocoon with evenly smooth silk fibers.

Comments.

The edges of the median area on T2 are not straight throughout, thus 1/3 proximally are straight, but afterwards are curved ( Fig. 190H ), the propodeal spiracle distally are framed with a short carina touching the pleural carina, the ventral furrow of the pronotum with parallel costate ( Fig. 190C ), most of the metepimeron with punctate sculpture, and the body is stout ( Fig. 190A ).

Male.

Unknown

Etymology.

Rafael (Rafa) Bolivar Manitio García is one of the Ecuadorian gusaneros who assisted with caterpillar rearing at Yanayacu Biological Station, Ecuador.
